View webinar: http://www.eurostarconferences.com/community/member/webinar-archive/webinar-77-the-search-for-surprises

In this talk, James Lyndsay will identify and illustrate approaches that help you to root out the ways that working software misbehaves. We'll put these approaches in context by describing emergent behaviours, strategies and diversity, wicked problems and the temptations of confirmation. Participants with laptops can download and work through some of the exercises.
